The English-language version of the first reference can be found on pages 388-399 of the above. This domain has been named NEW3 but its actual function is not known. It is found on proteins which are bacterial galactosidases [1]. The domain is associated with the NPCBM family, Pfam:PF08305, a novel putative carbohydrate binding module found at the N-terminus of glycosyl hydrolases.	Domain
